SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2026-03-28T20:24:00-CME-001 (version 1)

Note: Narrow CME first seen to the ESE in SOHO LASCO C2 starting at 2026-03-28T20:24Z. It is also seen to the ESE in SOHO LASCO C3 and GOES CCOR-1 but is covered by a real-time data gap in STEREO A COR2. This CME is very faint and is best seen in running difference imagery. There is no good source candidate on the Earth-facing disk, so that source is possibly far-sided.
